Allow Keywords with äüö...

Hello,
currently in PSPAD, if I specify a customized highlighter, the hightlighter will not recognize keywords which contain non ASCII characters as äüö.

The only text editor I found where this works is Textpad. Just I prefer PSPAD very much especially for the Hex editing and the superb file comparison functionality.

Would it be possible to upgrade PSPAD such, that keywords including such special characters are allowed?

This isn't as easy to realize it.
Is necessary to switch all user editor handling to unicode and store definitions in unicode or UTF-8.
I will put it into my todo list

Thank you!
